GRATE.

Application led February 2, 1923.

To all wimmelt mag/ concern Be it known that ERNEST BARFIELD, citizen of the United States, residing at Macon, in the county of Bibb and State of Georgia, has invented certain new and useful Improvements in Grrates, of which the following is a specification.

This invention relates to fuel burning devices, and more especially to what are known as grates such as are used in stoves, furnaces, heaters, fireplaces, and other like devices.

lore particularly, the invention relates to a cleaning device for grates in combination with a special form of dumping grate.

'One important object of the invention is to improve the general construction of devices of this character.

A second important object of the invention is to provide an improved cleaning device for grates of the basket type so arranged that all of the grate bars may, by a novel mechanism, be cleaned simultaneously.

A third important object of the invention is` to provide, in a grate of the basket type, dumping means so that the ashes and cinders may be quickly removed from the grate whenever desired. Y

A fourth important object of the invention is to provide an improved dumping means of this character so arranged that it may be renewed when desired, thus making the grate economical in use.

A fifth important object of the invention is to provide an improved cleaning and dumping arrangement for basket grates` so constructed that the cleaning arrangement may, if desired, be used to effect dumpingof the grate.

With the above and other objects in view as will be hereinafter apparent, the invention consists in general of certain novel details of construction and combinations of parts hereinafter fully described. illustrated in the accompanying drawings and specifically claimed.

In the accompanying drawings like characters of reference indicate like parts in the several views, and:

Fig. l0 is a detail section showing a part of the grate, the normal position being shown in full lines, the cleaning action of the cleaner being indicated in dashed lines, and the dumping position of the grate being indicated in dotted lines.

Fig. 1l is a detail showing the manner of suspending the cleaner.

Fig. 12 is a detail showing the manner of hanging the cleaning device on existing grates.

In the embodiments of the grate and cleaner herein illustrated, it will be seen that in each instance the grate is of the basket grate form, and is here shown as being set in a fireplace 10 in the detail figures, and in a Franklin stove in Figures 6 and 7. lt is to be noted particularly, however, that this same grate may be used in a cooking stove, furnace, a heating stove of any preferred type, as well as in fireplaces and Franklin stoves as illustrated.

This grate as constructed under the present invention includes the `front bars 11 which curve backwardly and have their lower ends bevelled as at 12, so that the bevelled ends 13 of the bottom bars 14.- may rest on these bevelled ends 12 when the grate is closed. These bottom bars 14 are all connected integrally with a rear bar l5, and the outermost bars 141- at cach `side of the grate are provided with pintles 16 which engage in vokcs 17 formed on brackets 18 secured to the side walls of the fireplace, whether the same be in an open fireplace, a stove, furnace or heater. By this means it will be observed that it is possible, without disturbing ythe remainder of the grate, to remove the bottom, and it is to be noted that this feature is an important one since it enables the bottom, which is the first part of a grate to burn out, to be renewed without disturbing the front.

The center bar 14 is provided on top of the bevelled end 13 with an eye 1,9 adapted for engagement for the hook of an ordinary poker so that this bar may be so engaged and the grate bottom formed by the bars 14 tilted fon the axis of the pintles 16, so as to assume the position shown in dotted lines in Figures 2 and 10, thus dumping the grate.

lt will be observed that the brackets 18 may be of any preferred form, being shaped and constructed to suit the particular location of the grate, and that on these brackets there `is also provided an upper bearing socket 20. These soc iets 2O receive the pintles 21 of hangers 22 which carry at their lower ends a rake bar 23 provided with a series of teeth 24 `which project upward between the bars 14 and 11 so that when the rake, thus formed, is drawn forwardly and upwardly, the spaces between the bars 14 and 11 are thoroughly raked. By means of this construction it will be observed that the raking attachment may be lifted free from the remainder of the grate whenever desired so that if this attachment becomes injured in any way, it may be replaced without replacing the other parts of the grate. lt may also be found advisable to place an eye 25 on the back end center bar beneath the same as indicated in Fig. 4 so that the poker may be hooked therein for dumping in case the eye 19 cannot be reached.

In the modiication shown in Figures 8 to 11, the same form of dumping grate is used, but ,from the ends of the back bar 15 of the grate bottom depend yoke members 27 which receive pintles 28 on the ends of the back bar 29 of the cleaning device. From this back bar extend downwardlv and forwardly the cleaning bars or rods 30 which are connected at their front ends by a front bar 31 carrying upstanding eye 32 for engagement by the usual bent poker. On this cleaning frame or rake are pivoted, adjacent the front thereof, supporting legs 33 which hang down so as to hold the cleaning frame above the hearth or fire pit when dropped. lilith this arrangement, cleaning is accomplished by simply engaging the eye 32 with the bent end of the poker and raising and lowering` the front of the cleaning frame so that the bars 3() pass between the bars 11 and 14, and clean the spaces from the accumulation of ashes and cinders. Furthermore, with this arrangement` the grate may vbe dumped by simply engaging the eye 32 with the bent poker end and drawing forward on the cleaning frame. This will cause the grate bottom composed of the bars 14 and 15 to revolve on its pintles 16. Land move the grate bottom and cleaning frame to the position shown in dotted Vlines in Fig. 10, thus dumping the ashes and cinders from the grate bottom.

It will be noticed that in each instance there is provided a cleaning fra-me having elements passing `between the grate bars for cleaning the spaces between said bars, the cleaning frame being pivoted for swinging movement.

There has thus been provided a simple and efficient device of the kind described and for the purpose specified.

It isobvious that minor changes may be made in the form and construction of the invention without departing from the material spirit thereof. It is not, therefore desired to confine the invention to the exact form herein shown and described, but it is desired to include all such as properly come within the scopeclaimed.

For instance, one of these'changes may be made so as to permit the device to be hung on existing grates, as shown in Fig. 12. It will there be'noted that in place of the supporting means previously shown the end bars of the cleaner are provided with hooks 34 which hang over the bac-lr bar `15 of the grate.

Having thus described the invention, what is claimed as new, is:

l1. The combination with a grate including a front fixed portion and a bottom tilting portion, each of said portions consisting of parallel bars, the bars of the bottom portion resting on the lower ends of the bars of the front portion upon the grate being positioned for burning fuel; of a cleaning frame including elements passing between the bars of the bottom and front of the grate, said cleaning frame being swingingly mounted in position relative to the grate to permit passage of4 said elements between said bars.

2. ln a grate of the class described, a series of vertically disposed parallel front bars extending downwardly and curving rearwardly at their lower ends, a back bar, a series of bottom bars extending forwardly and curving upwardly at their front ends and integrally formed with the back bar, the bottoni end of the front bars being beveled to support the cooperatively beveled front ends of the bottom bars, and means to pivotally support the set of bottom bars.

3. In a grate of the class described, a series of vertically disposed parallel front bars extending downwardly and curving rearwardly at their lower ends, a back bar, a series of bottom bars extending forwardly andv curving upwardly at their front ends and integrally formed with the back bar, the bottom end -of the front bars being beveled yto support the cooperatively beveled front ends of the bottom bars, means to 4. lin a grate of the class described, a series of vertically disposed parallel front bars extending downwardly and curving rearwardly at their lower ends, a back bar, a series of bottom bars extending forwardly and curving` upwardly at their front ends and integrally formed with the back bar, the bottom end of the front bars being shaped to support the cooperatively shaped front ends of the bottom bars, means to pivotally support the eet of bottom bars, comprising pintles on the outermost bottom bars, yoles fixed at the sides of the grate to receive said pintles and constitute bearings therefor, and a cleaning frame swingingly mounted on the grate bottom at the rear thereof and including elements adapted to pass between adjacent grate bars.

5. In a grate of the class described, a series of vertically disposed parallel front bars extending downwardly and curving rearwardly at their lower ends, a back bar,

a series of bottom bars extending forwardly and curving upwardly at their front ends and integrally formed with the back bar, the bottom end of the front bars being shaped to support the cooperatively shaped front ends of the bottom bars, means to pivotally support the set of bottom bars comprising pintles on the outermost bottom bars, yokes fixed at the sides of the grate to receive said pintles and constitute bearings therefor, other yokes depending from the back bar at the ends thereof, a cleaning frame back bar pivotally supported in said yokes, parallel bars extending forwardly from the cleaning frame back bar and positioned to swing in the intervals between the grate bar, and means to support the front ends of the parallel bars in raised position.
